Description

The even shower of drought resisting

Technical field

What the present invention relates to is a kind of device of the plant shower for drought resisting.

Background technology

The crops of using for drought resisting are drenched device, be mainly used for to disperseing moisture to reach the object of even moistening large area soil with spraying at a distance nearby, utilize sprinkler head injecting type can make moisture moistening on the top layer of soil to ground moistening, root system of plant moisture can be provided rapidly.Compare filling type drought resisting, injecting type drought resisting can prevent from excess moisture and be penetrated into depths, stratum causing waste, and therefore shower type drought resisting is the water-saving best drought resisting modes of people.It is all generally at soil surface setting pressure water pipe that people adopt shower drought resisting device, then injection water device is installed on water pipe, and injection water device can be to spray equably large-area soil as best, but general injection water device is difficult to the object that reaches such.Existing injection water device, the sprinkler head that can produce large area umbrella water spot having, has the sprinkler head that produces one direction horn-like water spot.Umbrella water spot is the most equal springy land, but the umbrella water spot area that the sprinkler head of umbrella water spot produces is too small, because the pressure of water pipe is certain, the pressure of water outlet has disperseed to surrounding multiple directions simultaneously; The injection water shower nozzle jet length of the horn-like water spot of one direction is far, because hydraulic pressure is concentrated, but water-moistened land area is little, inhomogeneous, and this has just produced waste moisture.We also see a kind of one direction injection water spot sometimes has again an interference bar constantly automatically to stir the water spray mode of injection water generation umbrella water spot, the distance that the injection water of this mode can reach out to distances, can produce again umbrella water spot simultaneously, reach the object of large area springy land, therefore such automatic water shower nozzle is adopted widely by people.But, phenomenon when we examine this automatic water-jetting shower nozzle water spray that has interference bar, although disturb bar constantly injection water to be disturbed and produces umbrella water spot, but this interference is also limited, disturb the umbrella water spot producing just to account in time part by it, still can not change the unidirectional character of injection water completely, that is to say, such injection water mode is still moistening inhomogeneous to soil, or is wasting water.Visible, injection water shower bath also has the space of a large amount of research and development.

Summary of the invention

For overcome general drought resisting shower bath can not Large-Area-Uniform springy land, ground shortcoming, in order using water wisely to reach again the object of drought resisting, I have invented a kind of shower bath: the even shower of drought resisting, it can produce the remote unrestrained water spot of rotation, has reached object even, large-area springy land.

The even shower of drought resisting the taked technical scheme of dealing with problems is: the even shower of drought resisting mainly comprises water inlet, two circle swivel bearing, outlet nozzle, speed setting unit etc., in bearing in water inlet, two circle swivel bearing, cylinder, outlet nozzle connect successively, in its middle (center) bearing cylinder with the fixing welding of outlet pipe, water inlet pipe with in bearing, between cylinder, is connected and reaches the non-leakage object of rotation by rubber ring in a pipe, outlet nozzle is oblique to be stretched out and slightly does space and bend and make the propulsive thrust of injection water that the power of rotation is provided.

It is to be provided by the pressure of feed pipe that the even shower of drought resisting can spray at a distance evenly water spot, and the pressure of feed pipe is larger, sprays far, and still, the structure of shower self is also the reason that determines injection water spot distance.On the soil of drought resisting, the number density that water pipe and shower are installed should be as far as possible sparse, with the object that reaches cost-saving, reduces drought resisting goods and materials, this shower that will be arranged on feed pipe can have remote jet power, has again uniform injection water distribution capability.If we can be remote injection fire hose energy automatic rotation, this sprays fire hose and just strafes as circumference so, in turn, moistening equably more large-area soil.We do the part that enters vertically upward sparge pipe bending a little to side, the fire hose that makes to eject has reached to side and has sprayed, but what this injection was just fixed sprays to side, do not produce rotation, because the propulsive thrust of the injection fire hose has been subject to the support of shaft.Our bending before and after jet segment has been carried out a little to the part of edgewise bend again a bit, the propulsive thrust that sprays so the fire hose has just departed from shaft, so jet just circles around shaft, spraying the fire hose also circles, in turn spray equably water spot to surrounding, large-area springy land.

The beneficial effect of anti-even shower is: the even shower of drought resisting utilizes inner tube rubber ring to be connected and fixed pipe and swivelling pipe, reaches the non-leakage object of rotation.The even shower utilization of drought resisting two circle ball bearing and space bending outlet nozzle combine and produce rotatable side and spray the fire hose, and jet length is far away, it is large, moistening evenly to strafe area, are the drought resisting devices of using water wisely and the equipment of saving.

The specific embodiment

Below in conjunction with accompanying drawing, the even shower of drought resisting is described further.

Fig. 1 shows the inside and outside portion structure of the even shower of drought resisting in the mode of profile in the middle of side.The feature that the even shower of drought resisting is different from other sprinkler head is that it can be also in automatically rotation in spraying water to distant place, and between whirligig, do not have to come because of high hydraulic pressure water seepage, the structure member of this rotation is two circle swivel bearings (1), and two circle swivel bearings (1) more have the stability of rotation than general individual pen swivel bearing.In bearing in two circle swivel bearings (1), cylinder (2) is that we utilize the tubulose position that can rotate and pass through the tubulose position of water, in bearing, outlet nozzle (3) is directly welded on the top of cylinder (2), the angle that outlet nozzle (3) is made about 45 degree obliquely tilts, and this makes it water can be sprayed to far distance; The delivery port of outlet nozzle (3) is flat is not truncate tubulose but the outlet of bevel pipe, and this makes it in the injection water of distant place, have part water spot diverse location on the way fall.In bearing, below cylinder (2), be oral siphon (7), High-Pressure Water in oral siphon (7) is through cylinder (2) in bearing, but in bearing, cylinder (2) is constantly to rotate, the connection that can not fix, if just do contact simply mouth to mouth, junction temporarily can be very accurate, can not come by water seepage, but due to constantly spin friction damage, seepage soon.In order to solve the annexation of cylinder (2) in the bearing of rotation and static oral siphon (7), we are placed in the middle of the seam of two pipes with a rubber ring (6), the latter half of rubber ring (6) is fixedly stained with inside, the first half of being connected on oral siphon and is put in bearing among cylinder (2), like this, in bearing, cylinder (2) just rotates around rubber ring (6).But do not have water between cylinder (2), to ooze out from rubber ring (6) and bearing why? originally, the water passing through from rubber ring (6) has certain pressure, this pressure is expanded rubber ring (6), this expansion makes cylinder (2) and the always state in being close to of rubber ring (6) in bearing, can not come by water seepage.In the process of water spray, in the bearing of rotation also there is friction with static rubber ring (6) in cylinder (2), but because cylinder (2) inwall in bearing is very smooth, be difficult to produce damaging with flexible rubber ring (6), and the thickness of rubber ring (6) can be so that the even shower of this drought resisting continuously can be not worn out with 1 year yet, or manufacturer can also be made into the product that can change rubber ring (6).Screw running-on (8) is arranged at oral siphon (7) bottom in Fig. 1, for connecting water feed pipe.Another technical problem that the even shower of drought resisting also will solve is the speed issue that regulates rotation.A speed regulator (5) is arranged at two circles ball bearing (1) tops in Fig. 1, and the friction head that in one of the elasticity compressing that it utilizes regulating spring and bearing, tin (2) do to rub reaches the object of adjusting rotary speed.Outer matrix section in Fig. 1 also has some fixed plastics shells (9), and this makes the even shower of this drought resisting become a compact entirety.

Fig. 2 is that outer surface of upper figure is overlooked in the high-altitude of the even shower of drought resisting.Fig. 1 can solve the annexation of cylinder (2) and oral siphon (7) in the bearing of constantly rotation of the even shower of drought resisting, but can not show the solid space shape of water spray pipe (3), Fig. 2 is exactly the plane vertical with the space plane of Fig. 1, shows and solves the structure that produces rotation.The even shower appearance of drought resisting in Fig. 2 is simple, only see and in fixed plastics shell (9), tiltedly stretch out outlet nozzle (3), the afterbody of outlet nozzle (3) slightly bends, this propulsive thrust that water outlet is sprayed can promote outlet nozzle (3) and constantly rotate around central axis, but this rotation likely speed is very fast, but the screw that people can twist on the speed regulator (5) of bottom reaches the object of adjusting speed.In the situation that feed pipe pressure is identical, the even shower of drought resisting can reach farther water spray distance, and an even shower of drought resisting rotates the arid lands that plane exceedes a mu of strafing that produce, flat and moistening even, the investment of having saved widely drought resisting equipment.
